ELECTRIC SOLENOID HYDRAULIC CONTROL VALVES
The hydraulic power supplied by the auxiliary pump enters the aluminum block manifold located behind
the left front panel of the mixer body. The hydraulic flow is divided to the different circuits found on the
machine (e.g. discharge door, conveyor). The valves are controlled electronically from the control console
located in the truck cab. In the event of power failure, the valves can be controlled manually by depressing
the button located on each end of each valve.
Auxiliary Circuit Filtration
Once hydraulic oil has circulated through the manifold valve
and the hydraulic cooler, it exits into a filter assembly locat-
ed near the hydraulic tank. This assembly filters all of the oil
supplied in the auxiliary pump circuit. The filter is a 'spin-on'
type of filter. The filter is removed by turning the filter body
counterclockwise until it is free from the filter housing. This
filter will require periodic service and replacement.
